Amygdalotomy, also known as amygdalectomy, is a form of psychosurgery which involves the surgical removal or destruction of the amygdala, or parts of the amygdala.It is usually a last-resort treatment for severe aggressive behavioral disorders and similar behaviors including hyperexcitability, violent outbursts, and self-mutilation.
Part of the thalamus' stimuli goes directly to the amygdala or "emotional/irrational brain", while other parts are sent to the neocortex or "thinking/rational brain". If the amygdala perceives a match to the stimulus, i.e., if the record of experiences in the hippocampus tells the amygdala that it is a fight, flight or freeze situation, then ...
Human brain in the coronal orientation. Amygdalae are shown in dark red. The amygdala (/ ə ˈ m ɪ ɡ d ə l ə /; pl.: amygdalae / ə ˈ m ɪ ɡ d ə l i,-l aɪ / or amygdalas; also corpus amygdaloideum; Latin from Greek, ἀμυγδαλή, amygdalē, 'almond', 'tonsil' [1]) is a paired nuclear complex present in the cerebral hemispheres of vertebrates.

“The amygdala was still activated the way it should be, but now the dorsolateral prefrontal cortex was also able to come online and exert influence, quieting down the amygdala signal, so it ...
The central nucleus can be thought of as the exit of the amygdaloid bodies through which the bodily responses that are associated with fear leave the amygdala. [12] It is the most peptide-rich region of the brain. [8] The amygdalofugal pathway connects the central nucleus of the amygdala to the brainstem.
In particular, the hippocampus, prefrontal cortex and the amygdala are affected. [5] [6] One class of stress hormone responsible for negatively affecting long-term, delayed recall memory is the glucocorticoids (GCs), the most notable of which is cortisol. [1] [6] [7] Glucocorticoids facilitate and impair the actions of stress in the brain ...
